When did the harmonium arrive in India?

Reed organs, the family of the harmonium, reached India in the 19th century with missionaries or traders, and Calcutta was their first centre of popularity. Dwijendranath Tagore played a harmonium in the 1860s in his private theatre at Jorasanko, Calcutta. Bengali manuals followed soon after: Sourindramohan Tagore's Harmonium Sutra in 1874 and Krishnadhan Banerjee's Harmonium Shiksha in 1899.
